[0027] like Figure 1 to Figure 11As shown, the present application discloses a smart lock for being arranged on a door body. Figure 2~Figure 5 As shown in FIG. 1 , the smart lock includes an outer lock housing 1, a pan head 2, a first driving mechanism 3 and a second driving mechanism 4. The outer lock housing 1 is provided with a mounting cavity 11 with an opening facing forward. The pan head 2 is arranged in the mounting cavity 11, and the pan head 2 includes a mounting seat 21 connected to the outer lock housing 1, a support frame 22 installed on the mounting seat 21 and a pan head body 23 arranged on the support frame 22. Figure 1 and Figure 2 As shown, an identification module 24 is provided on the gimbal body 23 .

[0028] like Figure 1~Figure 3 , Figure 6 and Figure 7 As shown, the smart lock further includes a vertically arranged fixing seat 5, the fixing seat 5 is fixedly connected to the outer lock shell 1, and the mounting seat 21 is fixedly connected to the fixing seat 5 and arranged vertically. Specifically, the outer lock shell 1 has a cavity 12 connected to the mounting cavity 11 behind the mounting cavity 11, and at least a portion of the fixing seat 5 and a portion of the second driving mechanism 4 are both located in the cavity 12.

[0029] like Figure 3~Figure 5 As shown, the first driving mechanism 3 is arranged on the support frame 22, and the power output end of the first driving mechanism 3 is connected to the pan head body 23 to drive the pan head body 23 to rotate around the first axis A. The second driving mechanism 4 is arranged on the mounting seat 21, and the power output end of the second driving mechanism 4 is connected to the support frame 22 to drive the support frame 22 and the pan head body 23 to rotate around the second axis B relative to the mounting seat 21. The second axis B extends in the up-down direction and intersects with the first axis A.

[0030] It is understandable that the recognition module 24 is usually arranged on the gimbal body 23, and the second driving mechanism 4 drives the support frame 22 to rotate around the second axis B extending up and down. Since the gimbal body 23 is arranged on the support frame 22, at this time, the second driving mechanism 4 will drive the gimbal body 23 to rotate left and right through the support frame 22, so that when the user's face rotates left and right, it can be accurately recognized by the recognition module 24 on the gimbal body, and the recognized face information is more complete. The first driving mechanism 3 can drive the gimbal body 23 to rotate around the first axis A intersecting with the second axis B. At this time, the gimbal body 23 can realize rotation in two directions, with a wide range of recognition, which can better meet the needs of users.

[0031] The controller is electrically connected to the first drive mechanism 3 and the second drive mechanism 4. The specific principle of the controller controlling the first drive mechanism 3 and the second drive mechanism 4 is the same. The control of the second drive mechanism 4 is briefly described as an example, as follows: when the recognition module 24 recognizes that the user is close to the left or right side of the gimbal body 23, the recognition module 24 transmits the recognized position signal to the controller. Since the controller is electrically connected to the second drive mechanism 4, the controller controls the second drive mechanism 4 to operate so that the recognition module 24 of the gimbal body 23 is aimed at the user, so as to achieve the purpose of accurate identification and / or unlocking. Since the specific control principle is the same as the principle of the controller controlling the operation of the drive mechanism in the prior art, it will not be described in detail in this embodiment.

[0032] The above-mentioned pan / tilt body 23 is a spherical head body, and the peripheral surface of the mounting cavity 11 is a spherical surface. Figure 3 As shown, the aforementioned pan-tilt body 23 defines a accommodating cavity 230 with an opening facing backward, and the support frame 22 is located in the aforementioned accommodating cavity 230. The aforementioned pan-tilt body 23 is located at the center of the mounting cavity 11, and the gap between the outer peripheral wall of the pan-tilt body 23 and the peripheral wall of the mounting cavity 11 is uniform. In addition, a sealing ring 2312 is sleeved on the outer peripheral wall of the aforementioned pan-tilt body 23 to form a sealed connection between the outer peripheral wall of the pan-tilt body 23 and the inner peripheral wall of the mounting cavity 11. The presence of the sealing ring 2312 always maintains a sealed connection between the pan-tilt body 23 and the mounting cavity 11 during the rotation of the pan-tilt body 23, preventing water, dust, etc. from entering the accommodating cavity of the pan-tilt body 23. In order to facilitate the installation of the sealing ring 2312, the outer peripheral wall of the aforementioned pan-tilt body 23 is provided with an annular groove 2311 for the sealing ring 2312 to be located therein.

[0033] In this embodiment, if Figure 4 and Figure 5 As shown, the extension direction of the axis of the power output end of the first driving mechanism 3 is consistent with the extension direction of the first axis A. The above-mentioned gimbal body 23 is connected to the support frame 22 through the connecting shaft 25, the first axis A is the axis of the connecting shaft 25, and the power output end of the first driving mechanism 3 is coaxially arranged with the connecting shaft 25. In this way, under the drive of the first driving mechanism 3, the gimbal body 23 rotates around the connecting shaft 25. In this embodiment, an assembly groove 220 is formed in the support frame 22, and the above-mentioned first driving mechanism 3 is a first motor located in the assembly groove 220.

[0034] In one embodiment, the connecting shaft 25 extends along the front-to-back direction. When the user tilts his head to the left or right, the recognition module 24 of the gimbal body 23 can recognize the user. However, due to the limited angle, the information of the user such as face recognition is incomplete. Combined with the left-right rotation of the gimbal body 23, the user information can be more fully recognized. Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the connecting shaft 25 extends in the left-right direction, and the second driving mechanism 4 is located behind the first driving mechanism 3. In this way, the pan head body 23 swings forward and backward by rotating around the connecting shaft 25, and can be recognized by the recognition module 24 on the pan head body 23 when the face is raised or lowered, which can also meet the needs of users of different heights and has a wide recognition range. In addition, the second driving mechanism 4 is located behind the first driving mechanism 3 to avoid the second driving mechanism 4 interfering with the first driving mechanism 3, and the arrangement is more reasonable, which facilitates the rotation of the pan head body 23 in two directions.

[0035] like Figure 5 As shown, the support frame 22 is provided with a limiting structure 221 for enabling the pan / tilt body 23 to rotate between a first position and a second position, and the first position and the second position are located on a rotation path of the pan / tilt body 23 rotating around the connecting shaft 25. It can be understood that the existence of the limiting structure 221 can better limit the rotation stroke of the support frame 22, thereby improving the reliability of the rotation of the support frame 22.

[0036] In one embodiment, the limiting structure 221 includes two limiting plates arranged at intervals along the rotation direction of the support frame 22. A convex portion 251 is convexly provided on the outer peripheral wall of the connecting shaft 25. The convex portion 251 is located between the two limiting plates. Figure 5 and Fig. 9 As shown, the limiting structure 221 is a limiting groove in which the protrusion 251 is located. The limiting groove is provided on the support frame 22. The limiting groove includes a first limiting plate 2211 and a second limiting plate 2212 arranged at intervals along the rotation direction of the connecting shaft 25. The first limiting plate 2211 is located below the second limiting plate 2212. When the pan / tilt body 23 is in the first position, the protrusion 251 abuts against the first limiting plate 2211. When the pan / tilt body 23 is in the second position, the protrusion 251 abuts against the second limiting plate 2212. In this way, the first limiting plate 2211 limits the first position of the pan / tilt body 23 to prevent the protrusion 251 from further moving toward the first limiting plate 2211; and the second limiting plate 2212 limits the second position of the pan / tilt body 23 to prevent the protrusion 251 from further moving toward the second limiting plate 2212.

[0037] like Figure 4 and Figure 5As shown, the above-mentioned smart lock also includes a first detector 2221 for detecting whether the pan-tilt body 23 is in the first position and the second position. The signal output end of the first detector 2221 is electrically connected to the controller, and the signal output end of the controller is electrically connected to the first motor. The controller is configured to: when the first detector 2221 detects a signal that the pan-tilt body 23 is in the first position or the second position, the first motor stops working.

[0038] It can be understood that the existence of the first detector 2221 can detect the position of the gimbal body 23. When the detector detects that the gimbal body 23 is in the first position and the second position, the signal is transmitted to the controller, and the controller controls the first motor to stop working. At this time, the gimbal body 23 stops rotating.

[0039] like Figure 4 , Figure 5 and Fig. 9 As shown, the connecting shaft 25 is provided with a first leg 252 and a second leg 253. When the pan / tilt body 23 is in the first position, the first leg 252 moves with the connecting shaft 25 to a position corresponding to the first detector 2221. When the pan / tilt body 23 is in the second position, the second leg 253 moves with the connecting shaft 25 to a position corresponding to the first detector 2221. The existence of the first leg 252 and the second leg 253 facilitates the detector to detect the position of the pan / tilt body 23 and accurately transmit the signal to the controller.

[0040] In this embodiment, the first leg 252 is located above the second leg 253. A first detection board 222 is disposed on the support frame 22, and the first detector 2221 is a detection switch disposed on the first detection board 222.

[0041] like Figure 1~Figure 3 As shown, the above-mentioned gimbal body 23 includes a spherical shell 231 with open front and rear sides and a cover plate 232 covering the front opening of the spherical shell 231. The cover plate 232 is connected to the spherical shell 231 by snap-fit ​​connection or screw connection. The recognition module 24 is arranged on the cover plate 232. The aforementioned recognition module 24 is at least one of a cat's eye 241, a screen 242, and a face recognition module. In this embodiment, the recognition module 24 includes a cat's eye 241 and a screen 242. In addition, a human body sensor or other functional parts may also be integrated on the gimbal body 23. The above-mentioned sealing ring 2312 is located on the spherical shell 231.

[0042] like Figure 3 , Figure 6 , Figure 8 and Fig. 9As shown, the second driving mechanism 4 includes a second motor 41 and a driving gear 42, the driving gear 42 is mounted on the output shaft of the second motor 41, and the support frame 22 is mounted on the mounting seat 21 through the mounting shaft 224, and is relatively fixed to the support frame 22. The second axis B is parallel to the axis of the mounting shaft 224 and is arranged at intervals. The support frame 22 is provided with a toothed transmission member on the side of the mounting shaft 224, and the driving gear 42 is meshed with the toothed transmission member to drive the support frame 22 to move back and forth between the third position and the fourth position, and the third position and the fourth position are located on the rotation path of the support frame 22 rotating around the second axis.

[0043] It can be understood that the second motor 41 drives the driving gear 42 to rotate. Since the toothed transmission member is engaged with the driving gear 42, the driving gear 42 drives the support frame 22 to rotate around the second axis B through the toothed transmission member. Since the gimbal body 23 is set on the support frame 22, at this time, the gimbal body 23 rotates with the support frame 22.

[0044] like Figure 6 , Figure 8 , Fig. 9 and Fig.11 As shown, the toothed transmission member is an arc-shaped rack 223 arched toward the driving gear 42, and the mounting seat 21 is provided with an arc-shaped groove 211 arched toward the driving gear 42. The mounting shaft 224 is relatively fixed to the support frame 22, and the mounting shaft 224 is inserted into the arc-shaped groove 211. The mounting shaft 224 on the support frame 22 moves along the arc-shaped groove 211, that is, the support frame 22 moves along the arc-shaped groove 211. In this way, the left and right swing of the support frame 22 is realized.

[0045] The mounting shaft 224 is a screw fixedly connected to the support frame 22. Figure 6 As shown, the mounting shaft 224 extends in the up-down direction, and there are two groups of mounting shafts 224 and arc grooves 211, which are arranged at intervals in the up-down direction. In this way, the cooperation of the two groups of mounting shafts 224 and arc grooves 211 can reliably realize the left-right swing of the support frame 22 and the pan / tilt body 23.

[0046] In this embodiment, if Figure 6 and Fig.11 As shown, the mounting seat 21 is formed with an assembly cavity 210 for accommodating the support frame 22, and the top plate and the bottom plate of the assembly cavity 210 are both provided with the above-mentioned arc groove 211. The two arc grooves 211 can be arranged opposite to each other or staggered. In this embodiment, the above-mentioned two arc grooves 211 are staggered.

[0047] like Figure 8~Figure 10As shown, the above-mentioned smart lock also includes a second detector 61 for detecting that the support frame 22 is in the third position and a third detector 62 for detecting that the support frame 22 is in the fourth position. The second detector 61 and the third detector 62 are both electrically connected to the controller, and the signal output end of the controller is electrically connected to the second motor 41. The controller is configured to stop the second motor 41 when the second detector 61 detects that the support frame 22 is in the third position or when the third detector 62 detects that the support frame 22 is in the fourth position.

[0048] In addition, the smart lock further includes a fourth detector 63 for detecting that the support frame 22 is in the initial position. The second detector 61, the third detector 62 and the fourth detector 63 are all located around the mounting shaft 224. In this embodiment, the second detector 61 is located on the left side of the third detector 62, and the fourth detector 63 is located behind the second detector 61.

[0049] like Figure 8~Figure 10 As shown, the bottom of the support frame 22 is provided with a first protrusion 225 and a second protrusion 226, and the first protrusion 225 is located on the left side of the second protrusion 226. The mounting shaft 224 is located between the first protrusion 225 and the second protrusion 226. The second detector 61 and the fourth detector 63 are located on the movement path of the first protrusion 225, and the third detector 62 is located on the movement path of the second protrusion 226. When the first protrusion 225 corresponds to the fourth detector 63, the pan-tilt body 23 is in the initial position. When the first protrusion 225 moves to the position corresponding to the second detector 61, the pan-tilt body 23 rotates to the left and is in place, and the second protrusion 226 is located in front of the third detector 62. When the second protrusion 226 moves to the position corresponding to the third detector 62, the pan-tilt body 23 rotates to the right and is in place.

[0050] In this embodiment, if Figure 3 , Figure 8~Figure 10 As shown, a second detection plate 6 fixed relatively to the mounting base 21 is installed below the mounting base 21 , and the second detector 61 , the third detector 62 and the fourth detector 63 are detection switches arranged on the upper surface of the second detection plate 6 .

[0051] In addition, an adapter plate is provided on the mounting seat 21, and the adapter plate is used to connect the circuits in the pan / tilt body 23 with the outside world.

[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
